Specification of Letters Patent. Application" filed October l'l, 1908. Serial No. 458,192.

- To all whom it may concern:

T Be it knownthat I, CHARLES W. DENNY, a resident of the city and county of Philadelphia and State 'of Pennsylvania, have invented an 1m rovement in Fireproof Structures, of whic tion. y a

The rincipal objects of my invention are: to ac itate erection, tov conbine strength with lightness, to increase the fire resisting qualities, and to avoid the use of centering and framework. n

I The structure embraces studs composed of concrete sheathed in metal and a wall or walls of metallic lathing and plaster carried by the studs. i

A part of my improvements relates to the construction of the studs whereby they may be erected with facility and the metallic lathing maybe easily and eifectively secured in place; another part relates .to 1 means for cross bracing the studs to enable fewer studs. to be used without unduly weakening the structure; another part relates to means for forming inclosed air spaces between the walls to increase the fire resisting properties, and yet another part relates to the connection of stud sections through different stories and to the su port by the studs of the floor beams.

In t e drawings: Figure'l is a horizontal sectional view of a portlon of a fire-prodf Wall embodying my invention; Fig. 2 is a side elevation of the samewith part of the plaster removed fromthe lathing on'one side; Fig. 3 is a side elevation, with part in section, of the means for connecting and supportingthe studs between diiierent floors or stories; Fig. 4 is a plan view with part'in section of a modified form of the means'for connecting and supporting the studs; Fig. 5 is a perspective view of apart of one of the cross braces or horizontal partitions; Fig. 6 is a plan View of one of the supporting shoes for the studs; and Fig. 7 is ahorizontal sectional view enlarged of part of one of the studsheaths.

The wall consists rimarily of vertical c0lumns or studs a and a artition b of lathing and plaster carried by t e studs on either or both sides. The studs a, as shown, consist of an outer tubular sheath of sheet'metal and These studs are provided with offsets to which the metalliclathing is secured. These ofi'sets are preferably longitudinal vertical ribs e. lprefer to form the tubular sheaths the following is a specificaconvenient cross section.

of sections ofslieet metal 0, a, a, 0 having their edges lap-seamed to form the vertica ribs e. This is shown in detail in Fig. 7 where the longitudinal edge f of one section 0. is lapped over the flange f of the next section 0. These stud-sheaths may be of any In Figs. land 2 Patented Aug. 3, 1909.

I have shown one sheath cylindrical, forming a cylindrical stud, and another sheath square forming a square stud. The'sheaths formed of the connected sections are arranged in upright ositions, at such distances apart as may e necessary to give the desired stren h, and are then filled with the concrete, as s own. Suitable means may be used, if required, for su porting the studsheaths at their ends an securing them at the top or bottom. For this purpose, I have shown the shoes g, ada ted to be secured to the base or roof, an provided with the tongues g extending into the end of the sheath. After the studs have been put in place the lathing h is fastened. This is laid vertically in sheets over the studs resting on the'ofisets or ribs (3, to which the sheets are fastened in any convenient manner, as by wires h l To facilitate the fastening of the lathing after the studs have been erected, the

ribs e are preferably furnished with a series of holes e.

i are metal pieces arranged between the 'walls I) b and extending from stud to stud. These pieces both serve to brace the studs laterally, and thus enable them to be placed farther apart than would otherwise be possible, and also,'when constructed as partitions, and particularly when arranged one above another within thespacebetween the walls I) b, to form dead air spaces and thus increase the fire resisting properties of the entire structure. For eonvenience l prefer to form the artition' t of sheet metfal j bent at the mid le into a 'rib i,which is'nbtched or split at the ends, as at 1' to engage the intermediate ribs e e of the studs to which such split ends are secured, as by the wires i Providing the stud-sheaths with four ribs e at 90 from one anothermor.e or less-both enables the lathing to be attached at right angles to form a corner, .as shown in Fig. 1, and also provides the means for securing the cross-braces or partitions i between adjacent studs=.

In Figs. 3 and. 4 I have shown means for connecting the stud-sheaths together between adjaoent stories to form a continuous stud and for supporting the floor beams on i yoke 7c and sheath ends, particularly before gated as shown to form a spring the studs. 91s a bracket to which the floor beams n are secured. This bracket carries a yoke, k which embraces a tubular sleeve m extending into the ends of the adjacent studsheaths. The sleeve-m is preferably corrusurface which will retain the sleeve in position in the the concrete is 'introduced. In Fig. 3 the bracket is of double form having arms on both sides ofthe yoke 7c to support floor I i beams on both sides of the stud; in Fig. 4 the bracket has but a single arm. The yoke 76 lies between the extremities of the sections of stud sheathin which-abut'against it and support itas is s own in Fig. 3; The ribs e which thus abut againstfthe yoke provide a strong support. v

What I claim is as follows:

Lina fire-proof structure, the combination-'jofafstud consisting of hollow tubular, sheathing of sheet metal filled with concretev and provided with offsets projecting from its 'metallic lathin surface and arranged at an angle to one another and' at a substantial distance apart, secured to said oflsets and forming an ang e or corner between them and extendmg in the opposite directions beyond said studs to for the body of the walls, and

a'body of plastic material carried'by said lathing.
